环渤海地区三省两市产业结构相似性分析

Analysis on the Similarity of Industrial Structure of Three Provinces and Two Cities Around Bohai Sea

环渤海地区是我国北方经济发展的重要支柱,在我国经济高质量发展进程中发挥着重要作用。环渤海地区地理格局比较紧凑,产业布局较为近似,在促进经济高质量发展阶段,三省两市产业优势各有不同,但内部差异仍较为明显。为此,在采用被广泛应用的结构相似性系数和克鲁格曼专业化指数来衡量环渤海三省两市产业结构相似度的基础上,引入区位熵指数,分析区域制造业分布情况,发现,环渤海地区产业结构内部差异明显,区域产业发展协调性差。因而,环渤海地区产业结构优化调整,需要大力发挥北京在科技创新产业方面的带动作用,以京津冀的“发展点”带动环渤海的“区域面”,着力打造三省两市各地区的优势产业。

The Bohai Rim region is an important pillar of economic development in northern China and plays an important role in the process of high-quality economic development.In the stage of promoting high-quality economic development,the industrial advantages of the three provinces and two cities are different,but the internal differences are still obvious.Therefore,based on the widely used structural similarity coefficient and Krugman specialization index to measure the industrial structure similarity of the three provinces and two cities around the Bohai Sea,the location entropy index is introduced to analyze the distribution of regional manufacturing industry.It is found that the internal differences of industrial structure in the Bohai Sea region are obvious and the regional industrial development coordination is poor.Therefore,in order to optimize and adjust the industrial structure of the Bohai Rim region,we need to give full play to Beijing's leading role in the scientific and technological innovation industry,to promote the"regional area"of the Bohai rim with the"development point"of Beijing,Tianjin and Hebei,and to strive to build the advantageous industries of three provinces,two cities and regions.
